Lollitopping is a common training term. Remove all but the top few nodes to resemble a lollipop. Michican you know this, why even pretend you don't? I've found it very helpful growing in closets/tents where there is one light and no side lighting. But again, it's done before the flip. Seems crazy to me to leave all those sites below and try to get light to them that will be a lot weaker than the light above because of physics. Almost useless light on the bottom.
I've done this a bit too but the stronger the lights I use are the less I take off on the bottom. And also sometimes it's strain dependant, my current grow is all one strain and it always produces fat dense lowers so I leave a bit more on.
With a 600 watt hps or a 315 cmh I strip all but the very few top nodes because other wise the penetration just isn't there to grow nice buds down lower after the stretch.
With the 1000 watt de I can get a bit more penetration. So I leave more on. I know you can't tell because of how thick the trellis is but there isn't much under that first level of trellis I do leave a bit more on the isle as they will get good light from being on the isle. I'll come back and post some pics after the leaf strip in a week. At that point you can better see what is going on with the plants as of now all the leaves make it hard to see.
I'm shooting for a 5x18ish canopy that is roughly 3 ft deep on each side of the room. We shall see this is my first time trellising this strain I usually stake them.
EDIT: all that being said the bottom 16-18 inches of my plants are stripped.
